III. In-Depth: Manufacturing Workflow of Large Square Water Tanks

Stepwise Manufacturing Diagram with Annotations:

Raw Material Verification → Sheet Cutting (CNC Laser) → Hydraulic Press Molding → Precision Welding (TIG/MIG) → Panel Assembly (Bolt-On/ Welded Modular) → Surface Passivation & Pickling → Pressure/Leak Testing (ISO 15848-1) → Final Inspection (QA/QC) → Logistics & On-site Installation

Materials: Only 304/316L food-grade stainless steel ensuring compliance with EN 10312:2002, giving maximum corrosion resistance and potable water safety.
International Standards: All processes conform to ISO 9001:2015, FDA, ANSI/NSF-61 – guarantee structural integrity, non-toxic welds, and longevity.

Why Stainless Steel? Advantages Over Conventional Materials

Food-Grade Hygiene: Passivated stainless surfaces avoid microbe colonization, ensuring potable water safety without liner/tar coatings (zero taste migration as per WQA tests).
Exceptional Durability: Service life of ≥30 years, even in aggressive industrial/urban environments; maintenance cycles are reduced up to 70% compared to steel or GRP tanks.
Corrosion & UV Resistance: Chromium/nickel alloys create a tough oxide layer, eliminating common internal leaching and external rust.
Structural Modularity: Square/rectangular bolted panels provide superior strength-to-footprint ratio, allow for all-site scaling and fast, seamless repair/expansion.
Thermal Stability: Maintains water quality under extreme temperatures (-30℃~+80℃) and rapid cycling conditions.

IX. Frequently Asked Questions (FAQ) on Large Square Water Tanks

1. What stainless steel grades are used in large square water tanks?

Food-grade 304 and 316L stainless steels are most common. 316L is preferred for harsher chemical/process environments due to its enhanced molybdenum content.

2. How is leakage prevented in stainless steel water tank rectangular assemblies?

By precision TIG/MIG welding, laser-cut sealing lips, and factory hydro-testing at 1.5x design pressure, as required by ISO 15848-1. Modular tanks use EPDM or food-grade silicone gaskets for every panel joint.

3. What installation standards apply?

Typical projects comply with EN 1993-1-6 (steel structures), ANSI/ASCE 7-16 (seismics), and local potable water codes. All onsite crews are ISO 3834 certified for welded structures.

4. Is thermal insulation available?

Yes, tanks can be provided with PU/rockwool foam up to 50mm thickness, reducing thermal loss by 90% and protecting water from freezing in subzero regions.

5. How is tank hygiene maintained long-term?

Stainless steel's passivated surface inhibits bacterial growth. Easy-to-open manways, smooth welds, and annual high-pressure cleaning allow for safe, simple disinfection per CDC guidelines.

6. Can I customize sizing or special inlets/outlets?

Absolutely. All large square water tanks are modular and support customized dimensions, penetrations, ladder access, sensors, and insulation.

7. Which industries benefit most from these tanks?

Municipal waterworks, chemical plants, food & beverage producers, fire safety installations, and data centers predominantly choose stainless steel tank systems for reliability, hygiene, and regulatory compliance.
